Htherto in `the erection of concrete -Walls the `forms uhave 'been erectedbetweena supporting timber lframe at each side of the mould` which ,latter has-been'builtup of sections 4or forms lheld apart the requisite width of Wall hollow distance pieces such as piping and he'll or `tietltogether against [lateral `.elsp'lacement by bolts through suchpiecesa-nd orifices inthe Wall of the forms or Wires threaded throuh sueh .pieces end oriflees, enti ,secured to f e supporti frame 'by Said Wires or by Wires threadedlrough other orifices Ain the frame walls and nailed' to or'twvstearoundconvenent members of `the supporting" "frame which method "has lbeen slow" and costly.

Figure '7 is an end elevation of the same? showing the angled end, and

Figure 8 is a perspective of the tie member.

The improved form is constructed of timber, preferably light, and consists of a rectangular frame of side rails 7 and end and intermediate rails k8 with face boards 9 affixed upon one face to form a flush inner face having locking pin orifices 10 therethrough the side yrails 7 and intermediate rails 8 and the end rails 8 having clamp leg orifices l11 therethrough. Said forms are e conveniently constructed to an externall size of tfeet by 2 feet andthe intermediate rails 8 are spaced 2 feet so that a frame may be i used on end and said rails will be coincidentwith the side rails of frames on their sides inthe opposite side wall of the mould.

In the edge face of one or both the rails 7 whichy will be disposed horizontally in erection transverse recesses may be formed about the locking pin orifices to receive the tie members so that, su erimposed frames may, meet and make a tig t joint.` y When convenient .the frames may be positioned vertically and slots 21 are made through theface boards alongside the intermediate rails to permit ofa tie member being passed therethrough and locked to said rail. bya pin passed through the .orificed end of the tie and said rail. H

a The .distance and tie member 12 of suit- ,able metal such as galvanized iron of requisite strength, length and width has lockin r pin orifices 13 therethrough near each end and. requisitely distanced y and preferably has each end angled as at 14. t

The clamp for holding and tightening the Vmeeting vertical ends ofithe forms together are preferably constructed vof round iron in one piece formed to .provide parallel side members 15 and 16 and one end 17 in the lsame plane and one side member 15` being shorter than the other 16which has an end piece 18 angled to about sixty degrees from the plane of the side members thus leaving one end open to permit `of the short mem- In erecting the forms to form a cavity mould for the wall to be cast therein parallel forms with iush towards each other are placed upon edgein tiers of courses at each side of a supporting and stiening vertical stud 20 preferably the full height of the -Wall to be cast, tie members 12 are laid upon the top edges of each course` of forms transversely of the cavity and with their orifices 13y coincident wi the orifices 10 in the top side or thenhorizontal upper rail of said forms the turned down or angled ends of said tie members embracing said rail and holding said members in position and preventing outward lateral displacement of the forms. When the next course of forms has been superimposed locking pins or passed through the bottom side rails 7 thereof the tie member and the top side rails ofthe lower forms and so lock the whole together, the tie members being of suflicient strength to hold the parallel forms apart the requisite width and being secured between and across said forms prevent Vlateral displacement thereof and hold or stiien the erected forms or mould 'in correct position during casting of the wall. v

The clamps are then a plied to the vertical or end rails 8 of the orms and the studs 20 by passing the short leg 15 of the clamp throu h the coincident orifices turning the angle end 18 of the clamp in a ainst the forms until it embraces one of t e rails 8 when a wedge 19 is driven between said end `18 and the rail 8 so clampingfthe forms and stud together and making a tight joint. y

After casting andsettin `of the wall the mould is disrupted as wel understood and the ends of the tie members projectin from each side of the wall are fractured o I claim:- u 1. A concrete wall erecting form,comprisj ing sectional frames each having faceboards on one side thereof ada `ted to forma flush face when assembled,t e vertical members of the frames being provided with apertures therethrou h, the apertures of one frame `being ada te to yaline with the apertures of a longitu inally spaced framev forthe reception of clamping members for releasably securing together the "vertical members of cident apertures and interposed between vertical members of said faunes, and thehorizontal members of said frames having exposed recesses in abutting faces tofreceive the `,maintaining said framesin verticalalinec .l c y ment. l

2. An open-ended clampV of lrectangular formation for concrete wall erecting forms, said clamp having a short leg, one end land frames abutting a vertical stud having coina longer leg in the same plane and an end integral with said longer leg and extending at an angle to the plane thereof.

3. A concrete wallmould comprising secf frame members` to maintain the moulds in vertical alinement, vertical studs having apertures coincident with the apertures in the vertical frame members of the forms interposed between said members, and clamping means through said frames and studs to secure them against longitudinal displacement.

4. A concrete wall mould comprising a pair of spaced parallel tiers of sectional forms having `vertical and horizontal frame ber, tie members having an a erture in each end interposed at each end etween superposed forms in each spaced tier with the aperture coincident with the apertures of said top and i-bottom` frame members, pins through said framemembers and tie member ends, vertical studs having apertures coincident with the apertures in the vertical `frame members of the forms interposed between said members, and clamping means through said members and studs to secure them together and against longitudinal displacement. i
